Description
Technical field:
The present invention relates to the production platform in offshore oil and gas field field, particularly relate to a kind of axisymmetric barrel base list lower limb post and adopt
Oil platform and construction method thereof.
Background technology:
Marine marginal field refers to that those reserves are little, outlying district, deep layer and the sea area of harsh environmental conditions, it is exploited
All income remains basically stable with the expenditure of exploitation, or income is the fewest.China offshore oil and gas Tanaka has quite a few to belong to limit
Oil gas field, the most cost-effective exploitation marginal field is always the problem that Offshore Engineering circle is concerned about.In order to exploit limit
Border oil gas field, need to consider that multiple means is to reduce construction investment, to reduce development cost so that it is can obtain certain economic benefit.
It was verified that the simple feature that ocean platform has simple in construction, steel using amount is few, it is possible to greatly reduce offshore oil and gas
The development cost in field, is particularly suited for the exploitation of marginal field.Existing multiple simple platform scheme, or platform weight is still
Bigger than normal, or manufacture, installation process the most comparatively laborious, and can not reuse or moving process is complicated, recycling
Expense too high.
Number of patent application: 201410215018.3 disclose a kind of bucket foundation list lower limb post production platform, and it includes cartridge type
Basis, bucket foundation is positioned under mud face, and horizontal truss is positioned at Ni Mianchu and joins end to end triangle horizontal plane, each junction point one
End face is respectively welded on bucket foundation, and other end is welded with sub-truss and gin pole;Gin pole is welded on by water
On the junction point that plane frame work connects and composes, gin pole bottommost welds with bucket foundation;Two sub-truss one end are divided
Not being welded on other two junction point, the other end is all welded on gin pole, and is positioned at water with the pad of gin pole
Below plane, more than mud face;Horizontal truss, sub-truss and gin pole form space tetrahedral structure;Boarding platform is positioned at
More than the water surface, centrally disposed column top;Job platform is positioned at above boarding platform, the top of centrally disposed column;Position
Cat ladder it is additionally provided with between boarding platform and job platform.The defect of this structure is: overall structure is asymmetric, gin pole position
The vertical load that the barrel base at the place of putting is subject to is relatively big, and the vertical load that other two barrel bases are subject to is less, in causing
The Vertical Settlement that at the stud of centre, barrel base produces is naturally larger than the Vertical Settlement of other two barrel bases, and basis is in peace
Easily produce differential settlement during dress and use and make production platform run-off the straight, and then affect the use of production platform;
It addition, said two sub-truss and gin pole weld together with barrel base, overall weight is relatively big, to lifting appliance
Elevating capacity requires height, is also unfavorable for that engineering terminates the floating of rear production platform, transition and recycling.
Summary of the invention:
In order to make up the deficiency of prior art problem, it is an object of the invention to provide a kind of axisymmetric barrel base list lower limb post and adopt
Oil platform and construction method thereof, its simple in construction, easy construction, recycling is convenient, good in economic efficiency, it is adaptable to limit oil gas
The exploitation in field, the exploitation for marginal field reduces development cost.
